    You are asked to match three songs with the performers who made those songs famous. if you guess, the probability distribution for the number of correct matches is:

    Probability .333 .500 0 .167
    number correct 0 1 2 3

    What is the probability you get:

    a) exactly one correct
    b) at least one correct
    c) exactly two correct
    d) compute the mean, variance and standard deviation of this distribution
